Abstract

一种双缸液压锤，包括锤头、锤头导轨、液压油缸、上砧块、下砧块、锤砧和机架，两个所述液压油缸单向并联分别垂直安装在机架的底座的立柱中，液压油通过液压油缸内的活塞杆施加锤锻压力，两个液压油缸通过分流管相互并联。有益效果：本发明通过采用液压油缸施加锤锻压力噪音低、能耗小，与同吨位空气锤相比造价低，操作方便灵活。

Description

双缸液压锤
技术领域
本发明涉及一种锻压设备的液压锤，特别涉及一种锻压设备的双缸液压锤，属于锻压机械领域。
背景技术
目前现有的锻压设备一般采用空气锤，其动力传递介质为空气，虽然能完成一般工件的锻压要求，但操作费力，能耗大，由于空气锤制造工艺复杂，成本较高，进排气噪音大，存在严重的噪音污染，对工作环境影响较大。
发明内容
发明目的：本发明的目的是提供一种能够减少噪音污染、降低能耗和成本，操作简单的双缸液压锤。
技术方案：一种双缸液压锤，包括锤头、锤头导轨、液压油缸、上砧块、下砧块、锤砧和机架，两个所述液压油缸单向并联分别垂直安装在机架的底座的立柱中，液压油通过液压油缸内的活塞杆施加锤锻压力，两个液压油缸通过分流管相互并联。
有益效果：本发明通过采用液压油缸施加锤锻压力噪音低、能耗小，与同吨位空气锤相比造价低，操作方便灵活。
附图说明
图1为本发明整体结构示意图；
图2为本发明液压油缸连接示意图。
具体实施方式
如图所示，一种双缸液压锤，包括锤头1、锤头导轨2、液压油缸3、上砧块4、下砧块5、锤砧6和机架7，两个所述液压油缸3单向并联分别垂直安装在机架7的底座的立柱中，液压油通过液压油缸3内的活塞杆8施加锤锻压力，两个液压油缸3通过分流管9相互并联。活塞杆8的顶端与锤头1的支撑板下端相接触。工作时操作换向阀，液压油同时打入两个液压油缸3内，使两个液压油缸3的活塞杆8同时升起，将锤头1沿锤头导轨2向上顶起。当锤头1升到指定高度，再操作换向阀油路卸载，使液压油快速回油箱，液压油缸3的活塞杆8随之回位，失去支撑的锤头1自然下落，利用自重由上砧块4对下砧块5上的工件进行锻打。根据需要还可以通过控制换向阀使油压油封闭在液压油缸3内，使锤头1停驻在机架7上的锤头导轨2的指定高度，再按操作要求控制换向阀操纵锤头1上升或下降，换向阀起控制开关的作用。本发明与同吨位的空气锤相比造价低，安装使用方便，噪音污染少，能耗仅为空气锤的10％左右，适用于金属工件毛坯的锻打加工。
